Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
Commonly used stainless steel solid welding wires include AWS ER308, ER308L, ER309, ER309L, R316, ER316L and ER2209, etc., which are widely used in stainless steel welding, chemical industry, shi...
The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
There is no difference in process between full argon arc welding and argon arc welding. Full argon arc welding is suitable for thin-walled small-diameter pipes (generally DN60 and below, wall thick...
There are some inherent problems in dissimilar metal welding that hinder its development, such as the composition and performance of the dissimilar metal fusion zone. Most of the damage to the diss...
